Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I just received my Blackstone oil analysis report back of my 04 996. It look s little different than others I've seen on Reenlist. Copper levels a little high. Local shop says this could be IMS concern. Blackstone says could be from wear-in as engine has less than 10K miles on it. I understand that it's a bit difficult to make a solid analysis without a trend, however I wanted to create this baseline. The oil that was analyzed was 12 months old and about 2,500 miles on it. The oil was Mobile 1 0W40 as the previous service was performed by Porsche. The car now has 9,500 Miles. Thoughts of the analysis? Thanks!

POST 2Original post

It may help if you tell us your year and model and the oil you use. Check out my UOA thread here https://rennlist.com/forums/996-foru...of-action.html

POST 3Original post

That's does not look like Mobil 0W40. It's one UOA. Change the oil again in about 1-2,000 miles and see if copper is going up, down, or flat.

Hi Ahsai, The car is an 04 996 as mentioned in the OP. The oil that was analyzed I assume was Mobile 1 as the service was performed by Porsche. However I was not the owner at the time. Thanks for link - I'll check it out.

Interesting. Those are really high values for zinc and viscosities. Phosphorus looks about right, maybe slightly high. Usually we see more classic shear breakdown.

POST 7Original post

Wondering where the molybdenum comes from...assembly paste or ??

I'm pretty sure Jake Raby has addressed this before. But I can't remember, nor can I search on the Rennlist app. I'll look tomorrow on my laptop if not answered sooner.

I'm thinking exactly the same. The zinc level seems to be even higher than DT40. Oops I missed that.

POST 10Original post

You guys make me smile. The best way to protect the engine is to drive the thing. Not short trips as you are doing. Blow some **** out of it every couple of days or daily. Put more miles on it and then have your oil tested again. You will see a notable difference.

POST 11Original post

All I can say is that in order for there to be an average, there have to be numbers above the average. ...and the oil has only done 2500 miles.

This is a source reference. Confirm exact model applicability in the original material.
